    Eliminate duplicate code in Cmm pipeline

    End of Cmm pipeline used to be split into two alternative flows,
    depending on whether we did proc-point splitting or not. There
    was a lot of code duplication between these two branches. But it
    wasn't really necessary as the differences can be easily enclosed
    within an if-then-else. I observed no impact of this change on
    compilation performance.
